Premium transparent UHMW polyethylene tape for industrial surface protection, offering superior abrasion resistance, low friction performance, and noise reduction in aerospace, automotive, and manufacturing applications.
3M™ UHMW Film Tape 5421 is a premium transparent polyethylene-based protective tape designed for industrial applications requiring superior abrasion resistance and low friction performance. This thin-caliper general-purpose tape creates an effective "slip plane" between surfaces, allowing contact without wear while protecting plastic and metal components from damage. The tape features a unique combination of Ultra-High Molecular Weight polyethylene (UHMW-PE) backing with rubber adhesive, making it ideal for tough impact wear and sliding applications where lubrication is not possible due to contamination concerns.
The 3M UHMW Film Tape 5421 measures 20 inches wide by 18 yards long with a total thickness of 6.7 mil, providing substantial coverage for various industrial uses. This tape is mounted on a 60# densified kraft paper liner with silicone treatment, making it easy to die-cut into various lengths and shapes for customized applications. The translucent backing offers excellent visibility while maintaining abrasion resistance superior to PTFE, with a low coefficient of friction that is surpassed only by PTFE itself. The tape operates effectively across a wide temperature range from -30°F to 225°F (-34°C to 107°C), ensuring reliable performance in diverse industrial environments.
Primarily used in aerospace, automotive, printing, and MRO industries, the 3M UHMW Film Tape 5421 excels in applications including conveyor guide rails, spray booth liners, tank and bin liners, drawer and cabinet slides, and protecting aluminum sheets on stretch-forming presses. The rubber adhesive provides excellent initial tack for immediate bonding to material surfaces, while the UHMW-PE backing helps reduce squeaks, rattles, and other noises caused by movement and vibration. With an 18-month shelf life and compliance with ASTM D3330, ASTM D3652, and ASTM D3759 specifications, this industrial-grade tape delivers long-lasting performance and proven solutions for demanding applications.
